impedence depends on how your sub is wired inside the box. when it comes to amplifiers some amps are not stable at certain ohm loads. if you wire a sub down to 1 ohm and the amp is not 1 ohm stable you could potentially fry the amp.
amps put out most power at certain ohm loads and you match a subwoofer/s voice coil/s to the amp. ie. A crossfire vr1000d puts out 1000 watts at 1 ohm, so you would want to buy a subwoofer that you can wire to 1 ohm(dual 2ohm) so you can get the 1000 watts from the amp.
My subs are 8 ohms... bridged on a 2 channel amp, so that makes the speaker ohms drop to 4 correct? And therefore my amp is more powerful correct?? How would i wire my subs different to drop them lower than 4 ohms being it is already bridged????? ~ Thanks~
So your saying I will always get the max. output of the amp according to the speakers ohms (if the amp is 2 or 1 ohm stable)how do you get 2 8 ohm subs down to 2 or 1 ohm/ohms with a 2-channel amp that is already bridged on them or is it the amp that's going down to 2 or 1 ohms?....................And also Example:It would be stupid to use an amp that is 2 or 1 ohm stable on an 8 ohm subwwofer????? Am I close...lol
